MANUFCTURE 0F PAPER.

To all whom fit 'ma/y concern.'

Be it known that I, JULES GERNAERT, engineer, asubject of the King of the Belgians, residin at Brussels, No. 13 Rue Ducale, in the Kingdom of Belgium, have invented new and useful Improvements in or Relating to the Manufacture of Paper, of which the following is aespeciication.

Processes for the manufacture of paper that cannot be imitated, for the manufacture of securities, title-deeds etc. are well known,

small sheets ofpaper or of fibrous materials cut out in various shapes, on the paper pulp or in the paper pulp during the manufacture of the paper. As, however, it is impossible, in. thus spreading in the paper pulp or stuff, these small bits of cut out paper, to distribnte them in a thoroughly uniform manner, and as the'distribution in question'is left to at the outside straight or curved bands con tainingthe said small bits of paper, it is impossible to obtain by ineans of the said quantity, the paper of which would be absocaiinot bev imitated, "is however the possithe bank note or the security is genuine,

parison with the original. It is therefore of the utmost importance for the manufacture of paper that ycannot be imitated, to be able to manufacture any quantity of pieces yor bands of paper, identical down to their minutestdetails, in which given starting points manner, not only as regards their shape, but also as regards their place and distribution on the paper. That condition is complied with by the present process, owing to the introduction between two still half-moist layers of paper pulp, -thin colored or uncolored linings, in the shape of bands which can be cut out., stamped out or perforated, and one oi' both faces of which could be printed with patterns which always recur. Owing to the use as an inner material of these bands, of thin sheets stamped out., cut out or perforated in accordance with recurring given patterns, it becomes possible, as will be readily understood, to produce paper bands 0r sheets of any length and in any de- Specication of Letters Patent.

sired quantity, identical with each other in every detail. By the introduction of the said bands into the pa er pulp or stuff and by the arrangement o the cut out portions, perforations, etc., through which the fibers of the two layers of pulp can join each other and become felted together, the position and the distribution of the inner material in the paper are insured, and the separation of the aper from the inner material is rendered impossible. As inner material can be used metal sheets with varied patterns, elatin sheets or collodion films, or pa er ands.

In the same way, inner bands with various patterns in elatin, collodion or paper films can be use as vehicular matters for the sheets of metal with various patterns. In that case it is advisable to arrange and to secure the metal sheets, before'the introduction of sheets or bands into the paper pulp,

at the predetermined points of the vehicularinaterial, in accordance with the ever-recurring arrangement. It is only owing to the use' ofthe said vehicular materials for very thin metal or .other sheets, that it becomes possible to distribute them'ina very uniform manner in the paper pulp, which would have been impossible if they were simply thrown in into it.

The nature of the vehicular materials selected can be, if desired, such that they would become dissolved on 'contact with the water contained in the paper pulp, so that the said vehicular materials become completely invisible in the finished paper, and that'only the metal sheets distributed in a uniform manner, are visible. To that end can be used as vehicular matter gelatin, collodion films, etc.

The invention accordingly consists in the several steps and the relation and order of each of the same with respect to one or more of the others thereof, which will be exemplified in the art hereinafter described, and the scope of the application of which will be indicated in the following claims.

In the accompanying drawings wherein is shown one method of carrying on this art, Figure 1 represents'a ribbon or band of any suitable material. Fig. 2 represents the front face of a bank note or the like containing tlic ribbon or band shown in F ig. 1. Fig. 3 is a rear face of the bank note shown in Fig. Q. Fig. 1 represents a stock certificate or the like.

Referring. to Fig. 1, 1 represents a band perforations 2 or ribbon or any suitable material having formed therein in any suitable manner. 3 represents a second band or ribbon also provided With perforations and positioned behind the band or ribbon 1 to which it may be secured in any suitable manner. 4 represents a design or figure formed of thin material and secured to the front of band 1.- Suitable designs or characters 5 maybe printed or ot erWise formed on the face of band 1 and also if desired upon the face of band 3.

Referring to Fig. 2 in which the band is represented as being positioned Within 'a bank note, 6 represents designs of any ap` propriate character printed on the outer front face of t-he bank note and arranged in such a Way as to cover certain parts of the designs, characters or perforations of the band or ribbon 1, thereby preventing the latter from being photographed. 7 represents any suitable design, which may be a Water mark produced in the body of the front face. 8 represents characters denoting the denominationl of the note printed upon the face of the note. l

Referring to Fig. 3, 9 represents suitable designs printed 011 the outer rear face of the note and arranged in such a way as to cover certain portions of the designs, characters or perfor-ations of the hand. 10 represents a design or a Watermark produced in the body of the rear face and correspend ing with, or combined With, the design or Watermark 7. Any suitable imprint as 11 may be provided if desired.

Referring to Fig. 4, l2 indicates the certificate proper having secured thereto a counter foil 13. 14 indicates the coupon sheet attached to the certificate 12 and consisting of a number of coupons, as indicated. Extending across the coupon sheet is a plurality of ribbons or bands similar to the bands above described, which are introduced into the paper pulp in such a manner that each coupon will contain a portion thereof. If desired, a band 16 containing the number of the share may be inserted in the pulp of which the certificate is formed. It will of course be understood that although the bands 15 run in a longitudinal direction, they can be made to run in a transverse direction without departing from the invention.

1n order to carry out the process, it is preferable to Work in the following manner: The inner material which may or may not be colored, and which may have any form obtained by cutting out, stamping out, perforation, dyeing, is placed on the paper pulp, and a second layer of paper pulp is poured on the same. When the pulp passes between the calendering rollers, the paper pulp is forced through thc holes and around the edges of the inner material, which reterial, such as gelatin or collodion films, or

very thin paper Whether prepared or not.

If inner bands with varied patterns are used as vehicular materials for lmetal sheets With varied or other patterns, in thesame way as in every other case, the said vehlcular materials can have the shape of leaves, bands, threads, fabrics, nets etc. and be dyed, or printed upon, in any desired man ner. When the printing is different on both sides of the inner material, either as regards the coloror the drawing, the colors which are visible by transparency inthe finished paper could be made to complement each other. In the same Way, the metal sheets could be dyed or printed upon by means of metal inks, or provided 'with a coating by electroplating process. The mass of paper containing theinner material, could be vprovided vvwith water marks or be itself lperforated, and in that case the inner metallic or other material could be uncovered at any predetermined point. Any desired patterns could also lie-printed specially on the inner material visible on the surface, by means of metallic or other suitable inks. The unlinished paper is cut to the desired dimensions, and one or' various patterns could be printed on it,|either before or after, on one or both sides, the said prints or the colors completing eachother by the shape or the color of the inner materials.
